Summary
The current status of the theory of X-ray edges is reviewed, including the predictions of threshold exponents by means of sum rules and the recent exact solutions of the Nozières-de Dominicis model.
Riassunto
Si fa una rassegna dello stato attuale della teoria degli spigoli negli spettri dei raggi X, includendo le predizioni di esponenti di soglia per mezzo di regole di somma e le recenti soluzioni esatte del modello di Nozières de Dominicis.
Резюме
